TLC300

Remote control RTU for MV distribution centers

Integrates the functions needed to remotely control a medium-voltage substation.

  • 1 to 16 cells
  • UPS supply 12–48 VDC
  • DNP3.0
Hardware Remote control RTU for MV distribution centers — TLC300

Every switching operation that requires sending someone out to an MV cell is lost time and avoidable risk. The TLC300 concentrates control of up to 16 cells in a single unit, with its own safety logic in each one, so opening and closing can be executed from the control center — or locally if needed — without depending on a technician on site.

  • 1 to 16 cells, without changing equipment

    Scales from a simple substation to a complex distribution center, expanding over Ethernet, RS232 or RS485.

  • Keeps operating without communication

    Each cell keeps its own local safety logic, programmable to IEC 61131-3; if the link fails, the unit keeps controlling and syncs once it's restored.

  • Everything in one unit

    Control, measurement, communication and protection concentrated in one unit, with fewer failure points than a distributed architecture.

  • Integrates with legacy or modern SCADA

    DNP3.0, MODBUS TCP/RTU and IEC 60870-5-104, as a multi-protocol gateway with no need to replace existing infrastructure.
